Because the aperture of air exit 35 is less than opening 321, so wind-force in the annular air groove 34 not only can flow from air exit 35, still can flow along annular air groove 34, enters into left filter chamber 301, carries out the blowback to filter screen 33 in left filter chamber 301, blows off the raise dust on filter screen 33 in left filter chamber 301, makes the raise dust fall into in the dust collecting bin 14 from left export 305.
Similarly, when the filter screen 33 in the left filter cavity 301 filters the dust, part of the wind power entering the annular wind groove 34 from the left filter cavity 301 also flows into the right filter cavity 302, and the filter screen 33 in the right filter cavity 302 is blown back to blow off the dust on the filter screen 33 in the right filter cavity 302, so that the dust falls into the dust collecting bin 14 from the right outlet 306.
When the filter screen 33 in the left filter cavity 301 filters the dust, the wind force of the left filter cavity 301 pushes the outer ring 50 on the inner connecting plate 31 of the left filter cavity 301, so that the outer ring 50 is pushed to compress the resistance spring 52 to move rightwards, the electric sheet 53 is further contacted with the conducting sheet 54 to conduct a circuit, and finally the vibrator 55 connected with the inner connecting plate 31 of the right filter cavity 302 is started to vibrate the filter screen 33 in the right filter cavity 302, so that the dust is shaken off.
Similarly, when the filter screen 33 in the right filter cavity 302 filters the dust, the electric sheet 53 is also pushed by wind to contact the conductive sheet 54 to conduct the circuit, and finally the vibrator 55 is started to vibrate the filter screen 33 in the right filter cavity 302 to shake off the dust.
